Single-Ended 300B Tube Amplifier - Mockup IIs

This is my first 300B tube amplifier. The power supply will be separate from the amp. The tubes are $1200 rrp TJ Full Music 300B/SE carbon plates. The 6SN7 is a 50 year Treasure. The audio output transformers are 30W Hammonds. The base is Mirbeau and the top and bottom plates are 2mm thick aluminum. Signal wiring is 0.7mm pure silver wire and super heavy gold plated speaker binding posts.
